I did this on Saturday. I got there at 9am which is later than I was planning, but got the last two tickets for the Saturday evening show. They were not together but they were Row B of the mezzanine on the opposite sides of the theater. Great view. I was probably 15th in line. They did still have matinee tickets after me and the line wasn't super long. But I would say 830 if you want to guarantee yourself a ticket.
